我有以下Scala代码：

maybeEvent.fold(
          logAndExecute(s"$key is not a triggered key")(().asRight[Exception])
        )(
          logAndExecute(s"$key is a triggered key")(storeAndPublishEvent(_))
        )

字符串
maybeEvent是Option[Event]的类型，logAndExecute看起来像：

def logAndExecute[T](message: String)(executor: => T): T = {
    logger.info(message)
    executor
  }

型
当maybeEvent是None时，我得到了两个日志：

key is not a triggered key
key is a triggered key

型
当我把代码改为

maybeEvent.fold(
          logAndExecute(s"$key is not a triggered key")(().asRight[Exception])
        )(event =>
          logAndExecute(s"$key is a triggered key")(storeAndPublishEvent(event))
        )

型
问题已解决。你能告诉我这里有什么不同吗？提前感谢！
